Hanging behind the front grille and in front of the oil cooler is a piece with an electrical connection that is presently held on by 2 zip ties.
Can anyone tell me what it is?
I know the photo is bad. It was taken from underneath the car looking up. The bumper cover is on the left and the cooler on the right
Thanks

 

My guess is that a previous owner installed a radar detector....

 

Ambient temperature sensor?

 

Thanks @Jon89 I found a "K40" on it and the K40 on that radar detector is identical. Dont know if it has the rest of the detector inside.
